您好，我在尝试访问报表服务器 url 时收到以下错误。如何将 Windows 凭据传递给 ssrs 报告。为了您的信息，报表服务器配置在不同的服务器中，因此它会要求身份验证才能登录。请帮忙。谢谢

你需要设置

ReportViewer1.ServerReport.ReportServerCredentials = new MyReportServerConnection();

你的MyReportServerConnection 实现是这样的：

private sealed class MyReportServerConnection : IReportServerConnection2        
    {
        [System.Runtime.InteropServices.DllImport("advapi32.dll", SetLastError = true)]
        public static extern bool LogonUser(
                string lpszUsername,
                string lpszDomain,
                string lpszPassword,
                int dwLogonType,
                int dwLogonProvider,
                out IntPtr phToken);

        public WindowsIdentity ImpersonationUser
        {
            get
            {
                // Use credentials from config file

                IntPtr userToken = IntPtr.Zero;

                bool success = LogonUser(
                  "reportusername",
                  "reportuserdomain",
                  "reportuserpassword",
                  9,//LOGON_TYPE_NEW_CREDENTIALS
                  3,//LOGON32_PROVIDER_WINNT50
                  out userToken);

                if (!success)
                {
                    throw new Exception("Logon user failed");
                }

                return new WindowsIdentity(userToken);
            }
        }

        public ICredentials NetworkCredentials
        {
            get
            {
                return null;
            }
        }

        public bool GetFormsCredentials(out Cookie authCookie, out string userName, out string password, out string authority)
        {
            authCookie = null;
            userName = null;
            password = null;
            authority = null;

            // Not using form credentials
            return false;
        }

        public Uri ReportServerUrl
        {
            get
            {                   
                return new Uri("http://reportserverurl/ReportServer");
            }
        }

        public int Timeout
        {
            get
            {
                return 60000; // 60 seconds
            }
        }

        public IEnumerable<Cookie> Cookies
        {
            get
            {
                // No custom cookies
                return null;
            }
        }

        public IEnumerable<string> Headers
        {
            get
            {
                // No custom headers
                return null;
            }
        }
    }
